DDI Development

DDI Development is a Polish custom software firm specializing in Django and Symfony frameworks. The company works with startups, enterprises, and nonprofits across web, mobile, and cloud solutions. While the source doesn't specify team size or founding year, client testimonials suggest long-standing partnerships—one client reports cooperation spanning "the last year," another cites "3 years" of work together. The company operates from Poland and mentions serving clients in the UK, USA, and Australia.

DDI positions itself around two customer archetypes: startups seeking turnkey product development with optimized tech choices, and enterprises needing dedicated teams for long-term scaling. For both, the firm emphasizes Agile methodology, direct developer access (no manager-only communication), and free bug fixes post-launch.

Services and capabilities

The core offering is custom software development across four categories: web solutions, mobile applications, cloud solutions, and enterprise software. On the backend, DDI works with Django (Python) and Symfony (PHP). For databases, they deploy MySQL, PostgreSQL, and MongoDB. Frontend uses HTML5, CSS3, jQuery, Angular JS, and Bootstrap. Mobile work covers iOS (Objective-C) and Android (Java), with cross-platform porting via PhoneGap. Cloud infrastructure spans Google App Engine, Microsoft Azure, and Amazon Web Services.

Specific domain experience includes e-commerce (custom CMS, payment gateways, geolocation), e-learning platforms (responsive design, multi-database architecture, API interfaces), and recruitment/HR systems (CRM, financial management, applicant tracking). The company also handles booking systems, telemedicine platforms, warehouse management software, document management, freight forwarding, and food delivery applications. Case studies name these as completed work, though details on client names and project outcomes are light.

DDI's process follows Agile sprints: general analysis and planning, design and iteration, functional releases for testing, and post-launch maintenance. The firm claims "one development day for free" as a proving ground, though terms are vague. Transparency mechanisms include Git repository access for clients to monitor code changes, plus access to testing servers and task-tracking tools. Free server monitoring and bug fixes are promised for one year post-launch.

How they work

The engagement model is flexible. DDI offers fixed-price projects for startups, dedicated teams for enterprises, and outstaffing (placing developers within client teams). Communication is direct—developers are available beyond project managers, and the firm emphasizes no language barrier in English. Pricing is not disclosed. The company works in sprints, with each iteration combining specification, implementation, and testing. Adaptive to scope changes mid-project, DDI uses standard project management tools and provides ongoing maintenance after product release.
